WRENCH.

Specification of Letters Patent.

Patented June 1, 1909.

Application filed June 1, 1908. Serial No'. 436,136.

invention is set forth in the following full,

clear, and exact description, terminating with clalms particularly specifying the novelty.

This'invention .relates to tools, and more especially to the handles and shanks of wrenches; and the object of the same is to produce a wrench whose-handle or shank is so constructed and connected with the head as to permit the tool to be used in cramped quarters where those of other shapes could not well be employed.

To this end the invention consists broadly in swiveling the head to. the shank on an axis standing at right angles to that of the nut or member which is'to be operated, and specifically in the construction of the shank and its handle-so as to adapt these parts to use in a great variety of places.

One embodiment of my invention is set forth in the following specification and illustrated in the drawings wherein- Figure 1 is a sideelevation of this wrench complete, showing all parts as standing in one plane; Fig. 2 is a similar view with-the head turned at right angles to the position shown in Fig. 1 and the handle slipped through the shank; Fig. 3 is a rear View with the head turned on its swivel so thatits plane is obliqueto the length of the shank; Fig. 4 is a rear edge view of the head; Fig.

5 is a side view of he head and its swivel,

the latter upset at its rear end; Figs. 6- and l are edge and face views of the washer.

In the drawings the letter A designates.

the head of this wrench which is here illustrated asof the type popularly known as alligator jaw that is to say, its opening flares outward and one side is smooth while the other side is notched, and its sides may be reinforced by webs a. From the base of this head in line with thejaws projects rigidly an integral pin P, best seen in full lines in Fig. 5, which passes transversely through an eye in the enlarged upper end S of the shank and is" headed or upset at the farther sidebf the eye as at p, awasher IV preferably-being interposed between said head and the eye of thefshank. The latter length. and having an enlargement S at its other end pierced with an eye parallel with the first eye. through which passes the handle H also herein shown as straight and having an integral littlCl/Z- at one extremity. Transversely into the eve S may be passed a set screw whose tip is adapted to engage the handle to hold the latter in any position to which it may be adjusted. although this set screw not absolutely necessanv. Through the other end of the handle is passed a removable pin C. and obviously loosened the handle can be entirely withdrawn from the shank.

In the use of this tool, the alligator jaw applied to a square or other shaped nut X manner illustrated in dotted lines in Fig. 1. from which it will be seen that the axis of said member is at right angles to the axis of the swivel P, and to tighten the nut there illustrated the remote end of the shank would have to he moved through the are shown by the large arrow, the" handle H moving bodily with it unless the handle be removed; if the presence of other fixed parts interfere with such movement of the handle, the latter may he slid through the eye S to the right as shown in Fig. 2 or to by removing the pin C the handle may be withdrawn entirely. Should the presence of other fixed parts yet prevent the movement of this end of the shank, the latter may be turned upon the swivel P so as to bring its end S' in Fig. l nearer to the reader or farther from himthereby causing this end to swing around the axis of the nut but out of a plane through said nut at right angles to the-axis.

In Fig. 2 is illustrated another use of this its swivel into a plane at right angles to the length of the shank and whuein the handle H is necessary. The jaws being applied to the nut N and the handle H preferably being drawn through the eyes as far as the pin C will permit, the nut N is turned by moving the head it to or from the reader n the position of the tool as shown in this v1ew such movement swinging the head A around the axis of the nut and causing the slfank S to move bodily with it and the handle H to turn around an imaginary center at which is v I m is here illustrated as straight throughout its when this is removed and the set screw s or other member which is to be turned, in a til the left until its head 71- strikessai d eye, or

tool wherein the head A has been turned onlll) theaxis of. the nut projected. Here again. the presence of fixed parts might prevent the use of'the handle in the position shown;-

when 'it'co'u'ld be slid to the left through the eye'S and its end carrying the pin G moved in the opposite'direction to produce the 'same.

result, or the handle Hcould be rer'noved entirely if the nut N were not so tight that it could not beturned by grasping the shank Sand moving the latter around the imaginary line at. a i

In Fig. 3 is illustrated still another use of this tool wherein the head A is set" on its swivel to a position where its plane is oblique to the length of the shank S, as necessary when the movement of the latter around the line n would be impeded by the existence of fixed parts, as will be under-.

stood. This tool is thereforeof particular merit by reason of its adaptability to use 1n cramped quarters where wrenches 4 whose .sha-nksare iigid with their heads conldnot be employed, whether the head andfs hank stood at right angles to each other, ins-a ling ment with .eachfother, or in a position with one oblique to the other.

I am aware that t 1s old broadly to connect I the head with the shank by a swivel or screw, andalso old to'use a'handle extending slid- .ably through a shank; but
